Transmission line form in high frequency PCB design
Both transmission lines and waveguides can be used as carriers for high frequency signal transmission, while microstrip lines and strip lines in TEM transmission lines and Substrate Integrated Waveguide in Waveguide structures are applied in the design of high frequency PCBs.
High frequency PCB wiring skills
The radiation intensity of the signal is proportional to the wiring length of the signal line. The longer the high-frequency signal lead is, the easier it is to be coupled to the components close to it. Therefore, the high-frequency signal lines such as the signal clock, crystal oscillator, DDR data, LVDS line, USB line, HDMI cable and so on are required to be as short as possible.
